.Application led July 8,

` The invention pertains generally to cook stoves or ranges and moreparticularly to a cooking top of a novel and advantageous character. Y y

The primary object of the Iinvention is to provide a new and improvedCookin(1F top for liquid and gaseous fuel stoves, adapted vto provide asmooth completely closed top when desired, and having one or moreopenings-therein closed by a. removable cover platewith means forsupporting utensils of varying sizes over the opening when the coverplate is removed.

Another object of the invention is to provide -a novel means forclosing' the vburner openings in the top. I

Still another object is to provide a cooking top whereby high heatingefficiency is attained. vOther objects and advantages will becomeapparent from the following descriptions and inA the accompanyingdrawings in which:

Figure 1 is a perspective View of a gas stove embodying the invention.

Fig. 2 is a plan view of the .preferred form of the invention.

Fig. 3 is a plan view of a closure for one of the cooking' apertures.

Figs. 4 and 5 are sectional views on the lines 4-4 and 5 5 respectively,of Fig. 2 looking in the direction of the arrows.

In the embodiment selected and shown herein for the purpose ofillustration, 'the invention is lincorporated in a gas range ofcustomary construction having a body G supported on suitable legs 7. Thebody has at one side an oven section comprising a broiler compartment 8and a superimposed oven compartment 9 and at 'the' other side a cookingtop 10 with a 4burner chamber formed beneath lit and containing aplurality of suitable burners (not'shown). A flue connection 12 maybelprovided in the usual manner to conduct away the waste gases from theburner chamber and the oven .section. The essential features of theinvention primarily reside in the construction'of the cooking top 10.

In the ordinary construction the cooking top comprises an open grid-workforming a number of spiders which are mounted over the burners.Obviously in such a construction a large amount of heat escapes throughthe open grid, thus lowering the heating STOVE.

closure will be flush with the upper and lower surfaces of the plate.

In the present embodiment the stove is provided `with a frame 13 havinga cent-ral` opening which is positioned over the burners. `The edges ofthe frame about the opening are rabbeted as shown at 14, Fig. 4,y toreceive and support the cooking top 10 which preferably comprises a flatlevel plate of a size and thickness to fit snugly in the rabbeted edges14 ofthe frame 13 with the upper ,surface of the top substantially flushwith the upper surface of the frame. Disposed about vthe cooking top area plurality of burner openings 15 positioned so that when the top Iismounted in the stove, an opening will be immediately above each of theburners. The burner openings are provided with a pluralityv of inwardlyextending radial ribs 16 Which form a utensil supporting spider. As maybe seen in Fig. 5, Vthe ribs are trapezoidal in cross section, the upperpart of the rib being the narrower partv of the trapezoid. Intermediateeach ib, the edge of the burner opening is cut away from the uppersurface to provide an inwardly extending flange 17. Thus a cooking topis provided in which a plurality of burner openings having utensilsupporting spiders therein may, if desired, be integrally formed fromcast metal.

It is frequently desirable in this type of cooking top to closefone ormore of the burner openings, either for the purpose of confining theheat to one opening or for providing a warming plate in which a utensilmay be warmed without coming in contact with an open flame. To this enda closure plate or lid 1S is provided foreach burner opening` which isarranged to fit in the opening in such manner that the upper and lowersurfaces of the closure are level witlrthe upper and lower surfaces ofthe cooking top. The plate 18, as shown in Fig. 3, is arranged to fitrelatively snugly within the burner opening 15, and is provided ivith aplurality of radial slots 19 Which, When the plate is positioned in theopening,

receive the' ribs 16. The side edges ofthe slots are beveled downwardlyto provide surfaces complementary to the side surfaces of the ribs.rihus, upon engagement ofthe ribs 16 with the slots 1 9,.a ivedgingaction v f iiange 2U is adapted to engage the flange 17 piojectiiiggvinwardly of the burneropening when the plate is positioned in theopening.l The plate may be suitably apertured,as at 2i, to receive ameans' for removing the plate from' the top. l

By the above, described construction a cooking top has been providedwhich is capable ofbeing entirely closed, by .means of the snuglyfitting closure plates, to providea Warming top, upon which utensilsmaybe ivarined orl slowly heated out of direct contact yvith the flame iMoreover, one or more of the burner openings may be opened to perinit a.utensil yto bel heated directly by the burner.`

the top, that burner opening will be partially or entirely closedthereby and in either event the remaining portions of the top will beheated by the hot gasesdeflected there across by the utensil.

Means has been provided in the present instance for insuring a morecomplete and etlicient heating of the more remote portions of thecooking top from any of the'burners. Since this heating is done almostentirely by the vpassing of the hot gases from the burner along` theunder surface of the cool;- ing top it becomes essential that there beyno projections thereon which would tend to obstruct the free flow of theheated `gas.

In order to provide a greater heatingsur-r face on theA lower surface ofthe plate, a large number of small pointed studs 22 are providedthereon. The studs 22 are formed Since the spider permits the uten?. silto rest thereon flush with the surface of the heated gases flow Without`materially hindering the free passage ofthe gases. lt will be seentherefore, since the surface to be heated is so great, and the cookingtop is relatively thin, that substantially all of theheat from the gasesWill be absorbed by oritransferred to the cooking topi.

rThe cooking' top as herein disclosed lends itself particularlyto a veryeconomical construction since it may be cast in onev piece. Moreover,the closures are so formed and mounted in the burner o jeninffs that no;artr l i :i

yAlthough the invention is susceptible ofk various modifications` andalternative cny structions', I have shown and herein described in'detailthe preferred embodiment but it is yto be understoodthat Ido not therebyintend to limit the invention to the specic form disclosed but int-endto cover `all modifications and alternative constructions yfallingWithin the spirit and scope of the invention as expressed in theappended claim.`

l claim as myvinvention:

n A stove' top comprising, in combination, a plate having` a circularburner opening therein, a plurality of ribs formed integral lvvith theplate and extending radially into said opening, said ribs beingequidist'antly spaced apart and terminating short of the axial center ofthe opening, 'and a lcover plate for said opening `having a plurality ofradially disposed slots havingtheir outer ends terminating in theperiphery of the cover plate, said'cover plate being adapted yto fitinto said openingy with its upper surface flush with the upperl surfaceof the top plate and with said ribsl entered iny said slots, said ribsrand slotsbeing of greater Width at their lower .edges than at theirupper edges whereby the ribs are adapted to engage and support the platethroughout f the Ilength, of the ribs.

In testimony whereof, I have hereunto aliXed my signature.
